Helicone

Helicone is an open-source observability and monitoring platform for developers building AI applications. It provides a unified AI gateway to route, debug, and analyze LLM calls across 100+ models from providers like OpenAI, Anthropic, Google, and more. Developers can access multiple models through a single SDK compatible with the OpenAI SDK, switching providers by changing the model name without code rewrites. The platform offers smart LLM routing with load balancing, automatic failovers, and response caching to optimize cost, speed, and reliability. It also includes tracing and debugging tools for visualizing multi-step agent interactions, real-time logging, and root cause analysis. Monitoring features provide unified insights across providers to detect hallucinations, abuse, and performance issues, with user metrics and alerting capabilities. Helicone is SOC 2 certified and HIPAA compliant, and can be self-hosted via single-click deployment or a production-ready HELM chart.
